LUCK-CASE Application :llt Jul 53.1907. Surisl No. 335,

To all whom ti may con-earn:

Be it knovvn that I, HENRY R. Towns, of hitter New Xork, in the count of New York and State of New York, have invented certain new and useful Improvements in Lock-Cases; and I do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enable ot .ers skilled in the art to which it epperteins to make and use the some.

My invention relates to on improvement in lock cases, and isdesigned more particularly as on improvement on the construction disclosed in my pending application No. 367,005 filed April 8th, 1907.

In my pending a )plicstion l have shown a padlock the case 01' which is composed of e body open at both sides and two concevo convex face plates, the body having seats and undercut shoulders and the face plates resting on the seats with their edges under the shoulders, the fece pistes being forced into such position b piressure applied to the outer convex faces 0 t e plates.

My present invention consists in providing the lock case with a seat, and an annular recess adjacent to the o ter edge of the seat,

views of the and securing the face plate on the seat by bending or expending a ring seated within the annular recess, over the outer edge of the face plate.

My invention further consists in the details of construction as will he more fully explained. and pointed out in the claims.

In the accompanying dmwings,'Figure 1 is a view elevation of a lock enibodfving'm invention. Fig. 2 is it view in elevation with one fees plate removed. Fig. 3 is e sectional view through; the lock. Y Fig. 4 is en enlerget view in section through a portion of the cat's ing end lots Fig. 5 is a view of e modifies tion; igs. 6, 7 and 8 are viev s of the securing ring. Fig. Sis a similerview of another modificetioni, and Figs. 10, 11 and 12- are ecurin ring shown in Fi s.-

1 represents a. loo case, which in thepres ent instenceis in the form of a ring and provided in its peripheral edge with two openings for the reception of the shanks or'ends 2 of the sliding end roteting shscsle 3. One

member of the sheelrleof this particular look, is adapted to enter one. opening end when Specification of Letters Patent.

noes the 1 ile t sest 4 extending around the casing, ind with an ennulau recess 5 formed in the shoulder 6.

7 are coin'evo-convex face plates covering the opposite feces of the lock. These plates- 7 are each held in place by the metal rings 8 which letter seated within the recesses 5 and overlap the edge of the plates. These rings may be secured in place before the face plates are placed in position, or the face plates may he first seated and the rings #3 applied. I

' When the rings 8 are applied in edvance of the face plate they ere expanded and forced into the recesses 5. Tl'iese rings may he sulliciently large to permit the face plates to be passed through onto the seats, and in such instances the face pistes are secured by either expanding or spinning the ring so as to cause it to overlap the edges of its face p or the latter may be secured in place by ex pending or fiettening the ooncsvo-convex faceplate. When the plate is secured by the method lest above described, 1 refer to spin the ring 8 down onto the face p ate to form a closed end weter tight joint.

As previously explained the lace pistes may be placed on their seats and secured by forcing the rings into their seats and n" ale-- sired, then expending or spinning the rings down onto the face pistes.

In the constructibnfshown in 5, the ring 8 employed is "lashape in cross section. This rin is pissed in position on the. seat t end. the lower portion'thereoi? is expanded or hulged outwardly as shown in Fig. 7 ssto enter the recess end thus lock the ring to the case. After the has been thus eiplied the fees piste is seated and locked by end ing down thenpper edge ofthe ring as shown in Figs. 5 end 8.

The construction shcwnin 9, l0, l1 and 12 is substantially the same as that shown in Fig. 5, except that the 5 is f. v T I some dists.ncei"ern.oved from the 4. both lnstencesythc by expending eportien the ring seat.

It is evident that menv sh might lie-resorted to in the r are looked in place into the nient of parts'shown end de will or departing from the spirit and --.*ope ol my HEVGDUOD. hence I would have it lorstood Q meme exact construction shown and described, but,

Hevi g fully described. my in'venticn what I chum as new and desireto secure by Letters--Patent,1e:

1. A lack compnsing a casing hzwmg e 2. A lock comprising e easing having a seat, a recessed shoulder, a face plate and a ring seetedin the recess in the shoulez' end overlapping the edge of the face plate.

In testimony whereof, I have signed this specificat-ien I'm the presence of ,two sub recessed shoulder, a face plate the edge of scribing witnesses. a which rests edgacent to the seul shoulder and HENRY! R. TQ'S IRE], a shouldered mug seated m the recess in said Witnesses:

shoulder and overlapping the edge of the face A; R. ERSKINE, plate.
